i have heard that platnum is no good for the turbo motors. my buddy swears they are better than my ngks can anyone clear this up for us

20 PSI is not doable on 93 octane. Simple math.
9 to 1 , which is what most 2.3 have, and 20 psi is like 14.5- 15 to 1 in a NA engine and 93 octane will not support a 14 or 15 to 1 engine no matter what people say they have done or know someone who has done. Feeding a bunch more of 93 octane fuel into a engine that needs 120 octane will just blow the engine. Because the fuel will self detonate at around 10.5 compression ratio. So if you would feed 93 fuel in a 14 to 1 engine the mixture would ignite about 50 degrees before the piston was at the top, You can see how this would not be good.
2.3 don't have a stronger crank assembly than the 2.5 or any other stock 4 cylinder. What it takes is a STEEL crank, canferred bearings and a strong oil pump. none of which the 2.3 has.
If I remember right the Turbo 2.3 mustangs were not any faster than the stock 302 GT, (which were an embarrassment) and the turbo’s were making around 3-5 psi.
20 psi in a engine with a cast iron crank and cast pistons will not work, No matter how or who says it will.

I would guess I have been building cars for longer than you, but that's a guess.
My first engine build was in 1962.

I think I'm done with this topic, I really don't care about 1/2 motor performance anyway.
